Definitions

  • the present invention relates to a printing apparatus and a printing method for printing images onto a web.
  • Examples of such currently-used apparatus include an inkjet printing apparatus (also referred to as an image recorder).
  • the printing apparatus includes a transport mechanism transporting web paper (web), and inkjet heads each discharge ink (ink droplets) onto the web paper to be transported for printing images.
  • inkjet heads are provided in a transportation direction of the web paper, and discharge ink in four colors individually for color printing.
  • the web paper sometimes serpentines when the transport mechanism transports the web paper. Such serpentine web paper causes misregister that an actual printing position is shifted from a target printing position. This causes a color shift that printing positions for different colors shift relative to one another.
  • Japanese Unexamined Patent Publication No. 2002-099178A a position of forming a latent image by an electro photographic printing apparatus is corrected.
  • US2012/0240803 discloses detecting the position of an edge surface of a web and predicting future position. Correction is carried out using using a meander-correcting part made of rollers that modify the position of the web.
  • the present invention has been made regarding the state of the art noted above, and its one object is to provide a printing apparatus and a printing method that allow suppression of misregister or a color shift upon printing of an image onto a web transported in a serpentine manner.
  • a printing apparatus according to the invention is defined in claim 1.
  • a plurality of printing heads of the printing apparatus according to the embodiment of the present invention is disposed in the transportation direction of the web, and a plurality of serpentine amount sensors is provided for the printing heads individually.
  • the serpentine amount sensors are provided for the printing heads individually. This allows suppression of the misregister and the color shift in the image printed with the printing heads.
  • the actually measured waveform data is composed of differential serpentine amounts obtained by calculating a difference between the serpentine amount detected by one of the serpentine amount sensors and a reference serpentine amount detected with another one of the serpentine amount sensors on either an upstream or downstream side of the one of the serpentine amount sensors in the transportation direction.
  • the predicted waveform data generating unit generates the predicted waveform data on the serpentine amounts to be produced in the following web in accordance with the actually measured waveform data composed of the differential serpentine amounts obtained by calculating the difference between the given serpentine amount and the reference serpentine amount.
  • the differential serpentine amount corresponds to a relative amount of the given serpentine amount and the reference serpentine amount. Consequently, the color shift can be suppressed more easily than that when the shift amount is determined only from the given serpentine amount.
  • the correcting unit corrects the printing position of the image by shifting the printing position with the printing head. Specifically, with an inkjet printing apparatus, the correcting unit performs correction such that ink to be discharged from inkjet nozzles in given positions is discharged from inkjet nozzles shifted in accordance with the shift amount. This achieves correction of the printing position of the image while no image data is changed.
  • the correcting unit of the printing apparatus corrects the printing position of the image by changing a positional relationship in the image data. Specifically, the correcting unit changes the positional relationship in the image data without shifting the printing position with the printing head. This achieves correction of the printing position of the image.
  • the serpentine amount sensor detects the serpentine amount caused by the transportation of the web.
  • the predicted waveform data generating unit generates the predicted waveform data on the serpentine amount to be produced in the following web in accordance with the actually measured waveform data on the detected serpentine amount.
  • the correcting unit corrects the printing position of the image in accordance with the shift amount, and applies the corrected printing position to the printing head.
  • the shift amount is determined with the shift amount determining unit in accordance with the predicted waveform data. Accordingly, the shift amount is determinable in accordance with the actually measured waveform data on the serpentine amount detected with the serpentine amount sensors more accurately than that through a method in which a shift amount directly determined. This allows suppressed misregister.
  • Figure 2 schematically illustrates an inkjet printing apparatus according to the embodiment of the present invention.
  • Figure 3 is a block diagram illustrating a positional shift corrector and control systems therearound.
  • Figure 4A illustrates web paper, pages in the web paper, a printing head, and an edge sensor when the printing apparatus of Figure 2 is viewed from above.
  • Figure 4B illustrates a serpentine amount, actually measured waveform data, a predicted serpentine amount, and predicted waveform data.
  • the numeral t denotes time.
  • An inkjet printing apparatus 1 includes a paper feeder 2, an inkjet printer 3, and a take-up roller 5.
  • the paper feeder 2 holds web paper WP in a roll form to be rotatable about a horizontal axis, and unwinds the web paper WP to feed it to the inkjet printer 3.
  • the take-up roller 5 winds up the web paper WP printed by the inkjet printer 3 about the horizontal axis.
  • the paper feeder 2 is disposed upstream of the inkjet printer 3 whereas the take-up roller 5 is disposed downstream of the inkjet printer 3.
  • the inkjet printer 3 includes a drive roller 7 upstream thereof for taking in the web paper WP from the paper feeder 2.
  • the web paper WP unwound from the paper feeder 2 by the drive roller 7 is transported downstream toward the take-up roller 5 along transport rollers 9.
  • a drive roller 11 is disposed between the most downstream transport roller 9 and the take-up roller 5.
  • the drive roller 11 feeds the web paper WP transported on the transport rollers 9 toward the take-up roller 5.
  • the transport rollers 9 are rotatable rollers with no drive mechanism.
  • the inkjet printer 3 includes a print unit 13, a drier 15, and an inspecting unit 17 in this order from upstream thereof between the drive rollers 7 and 11.
  • the drier 15 dries portions printed by the print unit 13.
  • the drier 15 includes a heat drum (not shown) with a heater embedded therein.
  • the inspecting unit 17 inspects the printed portions for any stains or omissions.
  • the drive rollers 7 and 11 and the transport roller 9 correspond to the transport mechanism in the present invention.
  • the print unit 13 includes a plurality of printing heads 19 discharging ink individually.
  • the print unit 13 also includes a plurality of (e.g. four) printing heads 19 (19a to 19d) along a transportation direction 201 of the web paper WP.
  • the printing heads 19 are formed by a first printing head 19a, a second printing head 19b, a third printing head 19c, and a fourth printing head 19d in this order from upstream thereof.
  • the printing heads 19 are individually spaced away from each other at a given interval in the transportation direction 201.
  • the printing heads 19a to 19d discharge ink in at least two colors, and allow color printing onto the web paper WP.
  • the first printing head 19a discharges ink in black (K)
  • the second printing head 19b discharges ink in cyan (C).
  • the third printing head 19c discharges ink in magenta (M)
  • the fourth printing head 19d discharges ink in yellow (Y).
  • the printing heads 19 are arranged in a width direction 202 (primary scanning direction) of the web paper WP substantially orthogonal with respect to the transport direction 201 (secondary scanning direction) across the web paper WP. Accordingly, image printing is performable without moving the printing heads 19 in the width direction 202.
  • the printing heads 19 each include a plurality of inkjet nozzles 20 in the width direction 202 for discharging ink.
  • the printing head 19 may be formed by nozzle parts 21 with the inkjet nozzles 20, the nozzle parts being arranged in line or in a staggered manner.
  • the printing apparatus 1 also includes edge sensors 23 (23a to 23d), and a positional shift corrector 25.
  • the edge sensors 23 each detect a serpentine amount (actually measured serpentine amount) MJ caused by transportation of the web paper WP.
  • the positional shift corrector 25 corrects a positional shift of the image to be printed in accordance with the serpentine amount MJ detected by each of the edge sensors 23.
  • the edge sensors 23 and the positional shift corrector 25 are to be described later in detail.
  • the edge sensors 23 correspond to the serpentine amount sensors in the present invention.
  • the printing heads 19a to 19d are simply referred to as the printing heads 19 if the heads are not particularly distinguished from one another.
  • the edge sensors 23a to 23d are simply referred to as the edge sensors 23 if the sensors are not particularly distinguished from one another. The same is applicable to the other components.
  • the printing apparatus 1 further includes a main controller 27 controlling en bloc the components of the apparatus 1, a storing unit 29 storing image data G to be printed, an input unit 31 used for operator's input setting, and a display unit 33 displaying an operation screen and the like.
  • the main controller 27 is formed by a central processing unit (CPU).
  • the storing unit 29 is formed by a ROM (Read-only Memory), a RAM (Random-Access Memory), or a storage medium such as a hard disk.
  • the input unit 31 is formed by a keyboard, a mouse, a touch panel, and the like.
  • the display unit 33 is formed by a liquid crystal monitor and the like.
  • Figure 3 is a block diagram illustrating the positional shift corrector 25 and control systems therearound.
  • the printing apparatus 1 includes the edge sensors 23, a collecting unit 41, and a predicted waveform data generating unit 43.
  • the edge sensors each detect the serpentine amount MJ caused by the transportation of the web paper WP.
  • the collecting unit 41 collects the detected serpentine amount MJ.
  • the predicted waveform data generating unit 43 generates the predicted waveform data HY on the serpentine amount MY to be produced in the following web paper WP in accordance with actually measured waveform data HJ on the detected and collected serpentine amount MJ.
  • the printing apparatus 1 further includes a shift amount determining unit 45 (see Figure 6 ) and a correcting unit 47.
  • the shift amount determining unit 45 determines a shift amount SF by which the printing position of the image is shifted in the width direction 202 of the web paper WP, substantially orthogonal to (intersecting) the transportation direction 201 of the web paper WP, in a direction in which the predicted serpentine amount MY is decreased in accordance with the predicted waveform data HY.
  • the correcting unit 47 corrects the printing position of the image in accordance with the shift amount SF and applies a corrected position to the printing heads 19.
  • the serpentine varies sequentially in its period and its amplitude. Accordingly, it is difficult to print the image to the serpentine web paper WP accurately. For instance, the actually measured waveform data HJ detected with the edge sensors 23a and 23b in Figure 2 does not almost agree with each other. Consequently, the misregister and the color shift cannot be suppressed sufficiently through the method in which the shift amount SF is directly determined from the serpentine amount MJ actually detected by the edge sensors 23 (e.g., actually measured waveform data of one period before).
  • the predicted waveform data HY on the predicted serpentine amount MY to be produced in the following web paper WP is generated in accordance with the actually measured waveform data HJ on the serpentine amount MJ, and then the shift amount SF is determined in accordance with the generated predicted waveform data HY.
  • the shift amount SF determined from the predicted waveform data HY causes less misregister or a less color shift than that with the shift amount SF directly determined from the actually measured serpentine amounts MJ. This is to be described hereinafter in detail.
  • the edge sensors 23 each detect the serpentine amount MJ caused by the transportation of the web paper WP. Specifically, as illustrated in Figure 4A , the edge sensor 23 detects a serpentine amount MJ at one of longitudinal side edges E of the web paper WP in the transportation direction 201.
  • the serpentine amount MJ corresponds to a variation amount of the web paper WP at the one side edge E in a width direction 202 substantially orthogonal to the transportation direction 201.
  • a transmission type or reflection-type photoelectric sensor having a light emitter and a light receiver is used as the edge sensor 23.
  • the edge sensors 23 are provided for the four printing heads 19 individually.
  • the edge sensor 23a is provided for the printing head 19a, and the edge sensor 23b is provided for the printing head 19b. Moreover, the edge sensor 23c is provided for the printing head 19c, and the edge sensor 23d is provided for the printing head 19d.
  • the edge sensor 23a detects the serpentine amount MJ at a setting position of the printing head 19a or around the position.
  • the setting position of the printing head 19a is, for example, a setting position of the inkjet nozzles 20.
  • the edge sensor 23a is disposed at the setting position.
  • the edge sensor 23a detects the serpentine amount MJ at the setting position of the inkjet nozzles 20 of the printing head 19a in the transportation direction 201 or around the setting position. That is for determining the shift amount SF1 with the serpentine amount MJ1 detected with the edge sensor 23a.
  • the edge sensor 23a is disposed upstream of and spaced away from the printing head 19a over the transport path of the web paper WP, as illustrated in Figure 2 .
  • the edge sensor 23a may be disposed adjoining to the printing head 19a.
  • the edge sensor 23a may be disposed downstream of the inkjet nozzles 20 of the printing head 19a.
  • Determining positions of the other edge sensors 23b to 23d are each the same as the determining position of the edge sensor 23a. Moreover, it is preferable that the edge sensors 23 are formed by the edge sensor 23a, the edge sensor 23b, the edge sensor 23c, and the edge sensor 23d in this order from the upstream of the web paper WP in the transportation direction 201. In other words, it is not preferable that the edge sensor 23a for the first printing head 19a is disposed downstream of the edge sensor 23b for the second printing head 19b.
  • the collecting unit 41 in Figure 3 collects the serpentine amount MJ, i.e., the actually measured waveform data HJ.
  • the collecting unit 41 is formed by a storing unit and the like for storing the serpentine amount MJ obtained with the edge sensor 23. Moreover, the collecting unit 41 collects the actually measured waveform data HJ1 composed of the serpentine amount MJ1 and actually measured waveform data HJ2 composed of a differential serpentine amount MJ2-MJ1, which is to be described later along with operation of the printing apparatus 1.
  • the predicted waveform data generating unit 43 generates the predicted waveform data HY on the predicted serpentine amount MY to be produced in the following web paper WP in accordance with the actually measured waveform data HJ on the serpentine amount MJ detected with the edge sensors 23 and collected with the collecting unit 41. See Figure 4B .
  • the actually measured waveform data HJ is time series data on the serpentine amount MJ1.
  • the predicted waveform data HY is time series data on the predicted serpentine amount MY.
  • the predicted waveform data HY is generated through a linear predicting method such as a Yule Walker equation.
  • Figure 5 illustrates the linear predicting method.
  • the predicted waveform data generating unit 43 firstly prepares P coefficients in advance in accordance with the actually measured serpentine amounts MJ. Then, the predicted waveform data generating unit 43 determines a predicted serpentine amount MY of one sample after using the P predicted coefficients and P serpentine amounts MJ. Such a process is repeated to generate predicted waveform data HY.
  • P actually measured serpentine amounts MJ are used for calculation.
  • P-1 actually measured serpentine amounts MJ and one predicted serpentine amount MY determined in the "prediction 1" i.e., total P serpentine amounts are used for calculation.
  • cells arranged in a vertical direction denoted by a numeral Q contain the serpentine amounts MJ each having the same numeric values. The same is applied to other line cells.
  • the predicted waveform data generating unit 43 updates the predicted coefficient for the linear predicting method used upon generation of the predicted waveform data HY every determination of the preset number of serpentine amounts MJ. This allows accurate generation of the predicted waveform data HY. Moreover, the predicted waveform data HY may be generated at a previous timing, such as a timing denoted by the numeral S in Figure 4B , set in advance for the detected serpentine amount
  • the shift amount determining unit 45 determines the shift amount SF by which the printing position of the image is shifted in the width direction 202 of the web paper WP, substantially orthogonal to (intersecting) the transportation direction 201 of the web paper WP, in a direction in which the predicted serpentine amount MY is decreased in accordance with the predicted waveform data HY generated with the predicted waveform data generating unit 43. It is assumed that one page corresponds to an area where one printing object (contents) is included. Under this assumption, the shift amount determining unit 45 determines the shift amount SF in accordance with the predicted waveform data HY, at the shift amount SF a misregister amount being minimized in a page R (see Figures 4A and 6 ) to be printed next.
  • the misregister amount is determined in accordance with the predicted serpentine amounts MY of the entire or partial predicted waveform data HY in one page as a representative value such as an average value or the median of the predicted serpentine amounts MY.
  • the shift amount SF is determined by multiplying the misregister amount by -1.
  • the page R may be next to the page where the edge sensors 23 detects the serpentine amounts MJ, or may be further next.
  • the correcting unit 47 corrects the printing position of the image in accordance with the shift amount SF determined with the shift amount determining unit 45, and applies the corrected position to the printing head 19.
  • the printing head 19 print the image whose printing position is corrected by the correcting unit 47.
  • the correcting unit 47 corrects the position by two ways, both of which are adoptable.
  • the following describes the first way. That is, the correcting unit 47 corrects the printing position of the image by shifting the printing position (printing formation position) with the printing head 19 in accordance with the shift amount SF.
  • the correcting unit 47 performs correction such that the ink to be discharged from inkjet nozzles 20 in a given position U is discharged from inkjet nozzles 20 in a position V shifted in accordance with the shift amount SF. Accordingly, the printing position of the image is correctable while the image data G to be printed is kept unchanged.
  • the correcting unit 47 corrects the printing position of the image by changing the positional relationship in the image data G in accordance with the shift amount SF. That is, the correcting unit 47 does not shift the printing position with the printing head 19, but changes the positional relationship in the image data G by editing the image data G to be printed. This achieves correction of the printing position of the image.
  • the correcting unit 47 does not only correct the printing position of the image but also controls a discharging position by fine movement of the printing head 19. Such may be adopted.
  • the following describes operation of the printing apparatus 1. Firstly, a method of correcting the misregister for the first printing head 19a is described, and then a method of correcting the misregister (color shifts) for each of the second to fourth printing heads 19b to 19d is described.
  • the edge sensor 23a detects a serpentine amount MJ1 caused by transportation of the web paper WP.
  • the collecting unit 41 collects the serpentine amount MJ1.
  • the predicted waveform data generating unit 43 generates predicted waveform data HY1 after the actually measured waveform data HJ1, i.e., the predicted waveform data HY1 on the predicted serpentine amount MY1 to be produced in the following web paper WP, in accordance with the actually measured waveform data HJ1 on the obtained serpentine amount MJ1 as illustrated in Figure 4B . Moreover, the predicted waveform data generating unit 43 generates the predicted waveform data HY1 per page.

  • the misregister amount is obtained by determining an average value of the entire or partial predicted waveform data HY1 in one page of the pages R to be printed.
  • the correcting unit 47 corrects the printing position of the image to be printed with the printing head 19a in accordance with the shift amount SF1, and applies the corrected position to the printing head 19a.
  • the shift amount SF1 is constant from start to completion of one-page printing. The same is applicable to the shift amounts SF2 to SF4.
  • the printing head 19a discharges ink in black (K) to print the image whose printing position is corrected. This allows suppression of the misregister of the image printed in black (K) with respect to the given position of the web paper WP.
  • the edge sensor 23b detects a serpentine amount MJ2 caused by transportation of the web paper WP.
  • edge sensor 23c for the third printing head 19c detects a serpentine amount MJ3.
  • edge sensor 23d for the fourth printing head 19d detects a serpentine amount MJ4.
  • the collecting unit 41 collects actually measured waveform data HJ2, mentioned later, so as to suppress a color shift between the image printed with the printing head 19a and that printed with the printing head 19b.

  • the actually measured waveform data HJ2 is composed of the differential serpentine amount MJ2-MJ1 obtained by calculating a difference between the serpentine amount MJ2 detected with the edge sensor 23b and the serpentine amount MJ1 detected with the edge sensor 23a, other than the edge sensor 23b, upstream in the transportation direction.
  • the actually measured waveform data HJ3 used for suppressing the color shift of the image printed with the third printing head 19c is composed of a differential serpentine amount MJ3-MJ1.
  • the actually measured waveform data HJ4 used for suppressing the color shift of the image to be printed with the fourth printing head 19d is composed of a differential serpentine amount MJ4-MJ1.
  • the predicted waveform data generating unit 43 generates predicted waveform data HY2 on the predicted serpentine amount MY2 to be produced in the following web paper WP in accordance with the actually measured waveform data HJ2 on the differential serpentine amount MJ2-MJ1. For instance, the predicted waveform data generating unit 43 generates the predicted waveform data HY2 per page. The predicted waveform data HY2 is generated through the linear predicting method.

  • the printing head 19b discharges ink in cyan (C) to print the image whose printing position is corrected. This allows suppression of the misregister of the image printed in cyan (C) with respect to the image printed with the printing head 19a.
  • the correcting unit 47 corrects the printing positions of the images printed with the printing heads 19c and 19d in accordance with the shift amounts SF3 and SF4, respectively.
  • the printing heads 19c and 19d discharge ink in magenta (M) or yellow (Y), respectively, to print the images whose printing positions are corrected. This allows suppression of the misregister of the images printed in magenta (M) and yellow (Y) with respect to the image printed with the printing head 19a.
  • the predicted waveform data generating unit 43 generates predicted waveform data HY2 on the predicted serpentine amount MY2 to be produced in the following web paper WP in accordance with the actually measured waveform data HJ2 on the differential serpentine amount MJ2-MJ1 obtained by calculating a difference between the serpentine amount MJ2 and the serpentine amount MJ1 as a reference.
  • the differential serpentine amount MJ2-MJ1 is a relative amount of the serpentine amount MJ2 and the serpentine amount MJ1 as a reference. Accordingly, the color shift can be suppressed more easily than with the shift amount SF2 determined only from the serpentine amount MJ2. The same is applicable to the serpentine amounts MJ3 and MJ4.
  • FIG. 7A is an explanatory view of an effect through the linear predicting method.
  • "serpentine 1" corresponds to the actually measured waveform data HJ on the serpentine amount MJ detected with the edge sensor 23.
  • "serpentine 2" corresponds to waveform data on the serpentine amount obtained from the color shift appearing in the image actually printed. It takes 200 ms (mm) until the serpentine amount detected with the edge sensor 23 appears in the printed image. That is, the "serpentine 2" has a phase lag of 200 ms from the "serpentine 1".
  • "serpentine 3" corresponds to predicted waveform data HY obtained by linearly predicting the waveform after 200ms when a phase lag occurs in the "serpentine 2".
  • Figure 7B is a comparative view between errors with no linear predicting and errors with linear predicting.
  • "error 1" indicates an error with no linear predicting and thus indicates an error between the "serpentine 1" and the “serpentine 2" in Figure 7A .
  • “error 2” indicates an error with linear predicting, and thus indicates an error between the "serpentine 3" and the “serpentine 2” in Figure 7A .
  • the "error 2" is approximately 80% less in value than the "error 1" and is close to the serpentine amount actually appearing in the printed image when the linear predicting is conducted. Consequently, the method of predicting the serpentine through the linear predicting method is found effective.
  • the edge sensors 23 detect the serpentine amounts MJ caused by transportation of the web paper.
  • the predicted waveform data generating unit 43 generates the predicted waveform data HY on the serpentine amounts MY to be produced in the following web paper in accordance with the actually measured waveform data HJ on the obtained serpentine amounts MJ.
  • the correcting unit 45 corrects the printing positions of the images in accordance with the shift amounts SF, and applies the corrected positions to the printing heads 19.
  • the shift amounts SF are determined by the shift amount determining unit 45 in accordance with the predicted waveform data HY. This allows determination of the shift amounts SF in accordance with the actually measured waveform data HJ on the serpentine amounts MJ detected with the edge sensors 23 more accurately than those by a method of directly determining the shift amounts. Accordingly, the misregister can be suppressed.
  • a plurality of printing heads 19 is provided in the transportation direction of the web paper WP, and the edge sensors 23 are provided for the printing heads 19 individually. Since the edge sensors 23 are provided for the printing heads 19 individually, the misregister of the image printed with the printing heads 19 can be suppressed. In addition, a color shift can be suppressed.
  • the predicted waveform data generating unit 43 generates the predicted waveform data HY per page to be printed. Accordingly, the misregister or the color shift can be suppressed per page to be printed.
